- the tactile projections are preferably of the same length. In other embodiments, the tactile projections are of different lengths.
- the invention also includes the technical teaching that in a locking core for a locking cylinder it is provided that the locking core has a profiled locking channel for interaction with a key, more precisely a side key profile, the locking core having at least one core pin hole which opens into the locking channel , and wherein the locking core has a receiving space for a scanning element for scanning an undercut, in particular a sufficiently undercut, profile rib of a key inserted into the locking channel, the receiving space having a base space in which a base body of the scanning element can be inserted or is inserted, and one has a projection space connected to the base space to form the receiving space, which laterally breaks through at least partially, in particular over 8 percent of the total length of the projection space, into the closing channel, into which a sensing projection of the sensing element projects when the sensing element is inserted, the base space and/or the projection space in In the direction of the axis of the core pin bore, a larger scanning dimension than the base body and/or than the sensing projection when the sensing element is inserted
- the scanning element of the locking core is designed as a scanning element described here.
- a locking core with a profiled locking channel and core pin hole, also with core pins and housing pins, generally with locking pins but without a receiving space, is basically known from the prior art.
- the receiving space is designed to accommodate a scanning element.
- the receiving space is adapted to the contour of the scanning element, with tolerances being provided so that the scanning element can be moved within the receiving space at least in one direction, preferably an axial direction, of the core bore.
- the receiving space has a base space that is adapted to the base body of the scanning element, and a projection space that is adapted to the tactile projection or tactile projections.
- the receiving space and the projection space are dimensioned larger in the axial direction of the core hole than the base body or the respective sensing projection, so that a degree of freedom for movement of the scanning element in the axial direction of the core bore is possible.
- the receiving space in the axial direction of the core bore is dimensioned to be one scanning dimension larger than the corresponding area of the scanning element. A space is thus formed for a stroke of the scanning element.
- the projection space breaks through into the locking channel, so that an (undercut) profile rib of an inserted profiled key can or projects through the locking channel into the projection space, more precisely into a sensing space which is defined in the axial direction of the core bore by the scanning dimension.
- the projection space and/or the scanning space breaks through laterally into the closing channel by at least 8 percent of the total length of the projection space and/or the scanning space.
- the lateral breakthrough is at least 10 percent, preferably at least 15 percent, even more preferably at least 20 percent and most preferably at least 40 percent of the total length of the projection space and/or the scanning space.
- the projection space/scanning space breaks through laterally into the locking channel.
- the scanning dimension or the scanning space is dimensioned such that when a key is inserted with a sufficiently undercut profile rib, the profile rib projects into the scanning space, in particular protrudes laterally into the scanning space, and when the scanning projection protrudes into the scanning space sufficiently undercut profile rib of the key, the outside of the base body at least in the area of the core pin hole is flush with the outer contour of the area of the housing pin and / or cylinder housing surrounding the core pin hole closes so that the housing pin is prevented from penetrating into the receiving space.
- the front part of the profile rib protrudes from the tip to the undercut, more precisely with an overhang of the undercut profile rib into the tactile area.
- the profile rib When used in the closing channel in the axial direction of the core bore, the profile rib has a profile dimension which is smaller or equal to, preferably approximately in the order of magnitude of the scanning dimension and smaller. Accordingly, the part of the profile rib between the tip or outer end and the undercut can protrude into the scanning space and be scanned there by the scanning element. Due to the undercut, an excess, projection or overhang of the profile rib is formed at the tip of the profile rib, which is queried or scanned in the scanning space.
- the sensing space is therefore not or only insufficiently occupied by the profile rib or the sensing projection does not strike the profile rib but rather the end wall of the projection space away from the base space.
- the base body therefore also borders on an inner wall of the receiving space and the flanks of the receiving space create an offset in the area of the locking pin, more precisely the housing pin, around which the housing pin can penetrate into the receiving space. This prevents the locking core from rotating in the cylinder bore of the locking cylinder beyond a certain angle of rotation when used in the locking cylinder. The angle of rotation is determined by the size of the recording space.
- the present invention allows the locking core to rotate back and not be caught in its twisted position.
- Sufficiently undercut therefore describes an overhang formed by an undercut, which occupies a scanning space in such a way that an adjacent scanning element inhibits rotation of the locking core from a predetermined angle of rotation.
- Such undercuts or corresponding overhangs have a dimension in the axial direction of the core pin bore which is preferably over 0.1 mm, more preferably over 0.2 mm and most preferably over 0.3 mm.
- the dimension is preferably smaller than 5 mm, more preferably smaller than 4 mm and most preferably smaller than 3 mm.
- An undercut profile rib is therefore always to be understood as a sufficiently undercut profile rib that has an overhang which the touch function can be implemented.
- the rib preferably protrudes through the side opening into the scanning space/protrusion space.
- the scanning element of the locking core is designed according to a scanning element described above.
- the receiving space of the locking core is adapted to the scanning element for receiving the scanning element with provision of the scanning space and movement back and away to the scanning space.
- the receiving space is preferably designed to be complementary to the scanning element, but also has the scanning dimension or the stroke, that is to say it is larger in the axial direction of the core bore than the scanning element or the scanning projection. This allows a linear movement in the axial direction of the core hole.
- the invention includes the technical teaching that in a scanning mechanism for a locking cylinder, with a locking core which has a locking channel into which a corresponding key can be inserted, which has at least one core pin hole designed as a through opening and which has a receiving space in which a scanning element is accommodated, it is provided that the scanning element has a core pin receptacle aligned with the core pin bore, a core pin being receivable and/or accommodated in the at least one core pin bore and the core pin receptacle, the receiving space forming a sensing space which breaks through into the locking channel or protrudes into the locking channel, so that a corresponding key section of a key inserted into the locking channel protrudes or can protrude into the sensing space, so that the scanning element in the area of the sensing space strikes or can strike against the corresponding key section protruding into the sensing space, the sensing space being dimensioned in this way that if the corresponding key section has a sufficiently undercut profile rib, the scanning element
- the scanning element is designed according to a scanning element described here.
- the scanning mechanism works as follows.
- a key is inserted into the locking channel of the locking core.
- the front part of the profile rib protrudes, preferably the bowl section from the tip to the undercut of the profile rib, especially the overhang, into the sensing space.
- the key section or overhang protruding into the sensing space, the key section adjoins the sensing projection associated in the axial core drilling direction.
- the scanning element is pressed outwards in the axial direction of the core bore towards the wall of the cylinder bore, thereby preventing an offset between the outside and the flanks of the receiving space.
- the housing pin adjoins the outside without preventing rotation of the locking core in the cylinder bore.
- the rotational movement is blocked from a certain angle of rotation.
- the key without a (sufficiently) undercut profile rib is inserted into the locking channel.
- the corresponding profile rib protrudes at most into the sensing space to a small extent, whereby the corresponding sensing projection rests either on the end wall of the sensing space or on the part of the profile rib that is not (sufficiently) undercut that is not sufficient for blocking.
- a shoulder is formed in the area of the outside of the base body to the adjacent circumference of the cylinder core, so that the housing pin can partially penetrate into the receiving space and a rotational movement is blocked by abutting the flanks of the receiving space from a predetermined angle of rotation.
- the locking core cannot be rotated further in a direction to open, but only back to the starting position in which the key was inserted into the locking channel.
- the receiving space is preferably designed symmetrically to the core bore, so that rotation in and counterclockwise is possible, limited by the corresponding dimension of the receiving space.
- the core pin is always accommodated in the core pin receptacle of the base body.
- the core pin penetrates the core pin receptacle of the base body and protrudes over the base body in the direction of the key.
- the core pin closes with the outer contour if there is a sufficiently undercut profile rib on a key in the twisted state or protrudes beyond the outer contour of the outside if there is a key with an insufficiently undercut profile rib.
- the core pin adjoins the wall of the locking core bore on the outside of the base body.
- a pin element prestressed in the direction of the locking core acts in the direction of the scanning element.
- the pin element is designed as a locking pin with a core pin and a housing pin.
- the housing pin is via a spring preloaded and pushes towards the cylinder core, which also forces the core pin in the same direction.
- the spring and housing pin are accommodated in a corresponding receptacle in the cylinder housing.
- the core pin is accommodated in the core hole of the locking core. Without the key inserted, the housing pin protrudes into the core hole. The core drilling continues from the receiving space towards the center of the locking core. Accordingly, the housing pin is always forced into the receiving space unless an inserted key counteracts it.
- a further embodiment provides that the locking core is designed according to a locking core described here.
- a locking cylinder comprising a cylinder housing which has a locking core bore in which a locking core is rotatably accommodated
- the locking core has a locking channel and at least one core pin bore opening into the locking channel

- the locking core has a receiving space with a sensing space in which a sensing element movable axially to the locking core bore is arranged, the sensing element having a core pin receptacle aligned with the core pin bore for receiving the core pin, the receiving space being at least partially broken through in the area of the sensing space to the locking channel, in particular closed at least 8 percent of the total length of the scanning space and/or the projection space is pierced laterally
- a scanning mechanism is provided according to a scanning mechanism described here.

- a further example provides that the undercut is dimensioned in the axial direction of a locking core bore such that a scanning element adjacent to a profile rib having the undercut is flush with an outside of the core pin on another side.
- the invention includes the technical teaching that in a method for scanning an undercut profile rib of a key inserted into a locking channel of a locking core, in particular a locking core described here, a locking core described here, a scanning mechanism described here, a locking core described here, a locking core described here Locking cylinder and / or a locking system described here, it is provided that the steps include: inserting a key into the locking channel of the locking core, so that a key section, in particular a side key section, protrudes into a tactile space of a receiving space of the locking core, during insertion in the case that the key has a sufficiently undercut profile rib on the section that protrudes into the scanning space, the scanning element movably arranged in the scanning space is contacted and the scanning element is moved towards the outside of the locking core, so that the scanning element is flush or almost flush with the outside of the Locking core closes and in the event that the key in which the key section that protrudes into the scanning space does not have a sufficiently undercut profile

This has a scanning dimension A in the axial direction of the core (pin) hole (see Fig. 11 ), which is the height of the sampling space 176 or the stroke H (see Fig. 15 ) of the scanning element 170 is defined or corresponds to the stroke H.

- the tactile projections 182 are cylindrical.
- the tactile projections 182 are arranged diametrically opposite and spaced apart from one another on the inside.
- the base body 181 has the receptacle 183 centrally for receiving the core pin 21.
- the receptacle 183 designed as a through hole, penetrates the base body 181 from a front side section 184 of the outside 185 towards the inside 189.
- a bevel 186 On the side of the outside 185 on each side there is a bevel 186, which is beveled at a first angle a to the front side section 184 adjacent. This is followed by another bevel 187, which is beveled at a second angle b. Due to the multiple bevels 186, 187, the scanning element 180 is optimized for contact with the housing pin 23 or an inner wall of the cylinder bore 120. In other embodiments, multiple slopes 186, 187 may be provided.

- the undercut profile rib 15a with the formed oblique projection, more precisely with the overhang 15b presses against the sensing projection 182 of the scanning element 180
- the scanning element 180 is pressed outwards accordingly and is thus flush with the outer contour of the locking core 130.
- the core pin 21 is flush with the scanning element 180, so that the core pin 21 can rotate with the locking core 130, as shown on the right Fig. 11 shown based on the twisted position.
- the overhang 15b of the (sufficiently) undercut profile rib 15a which is formed between the tip of the profile rib 15a and the undercut 17 of the profile rib 15a, is dimensioned such that it forces the scanning element 180 outwards accordingly, so that the locking core 130 can be rotated. Without this (sufficiently dimensioned) overhang 15b, twisting is only possible to a limited extent, as shown Fig. 12 visible.

- the significance of the missing overhang 15b becomes apparent in the twisted situation. Due to the missing overhang 15b, the forward stop for the scanning element 180 is missing.
- the scanning projection 182 is forced further inwards, so that the core pin 21 protrudes beyond the scanning element 180 and an offset 179 is formed on the receiving space 170, in which the locking core 130 forced housing pin 23 penetrates.
- the angle of rotation c can be adjusted via the geometry of the recording space 170 together with the scanning element 180. The following figures make it clear how the dimensions are to be determined to achieve the scanning function.

- Fig. 14 shows schematically in a front view an embodiment of the scanning element 180.
- Fig. 15 shows schematically in a sectioned front view a key profile of the key 10 with a (sufficiently) undercut profile rib 15a, that is to say with an overhang 15b.
- Fig. 16 shows schematically the embodiment in a sectioned front view Fig. 11 in a starting position and in a twisted position. The steps for determining are numbered in the figures.
- D denotes the height of the projection space 174 from a constructive center line of the closing core 130 in the axial direction of the core (pin) bore 160 to the stop at the end of the projection space 174.
- E denotes the length of the projection space 174 in the axial direction.
- F denotes the Total height of the scanning element 170 in the axial direction of the core (pin) bore 160.
- G denotes the height of the sensing projection 182 in the axial direction of the core pin bore 160.
- I denotes a width or key shaft height I of the key 10 in the axial direction of the core pin bore 160, more precisely of the key profile.
- H denotes the height of the overhang 15b in the axial direction of the core pin bore 160, which, in contrast to a non-undercut profile rib 15, results from the undercut 17 and which determines the height of the stroke and thus the scanning dimension A.
- the receiving space 170 has the dimension H+ in the axial direction of the core pin bore 160, i.e a dimension H increased by a tolerance. This dimension H+ should be at least equal to, preferably slightly larger than, the dimension H in order to ensure that an offset is guaranteed if the profile rib 15 is not sufficiently undercut.
- H+ is approximately in the order of magnitude of H or A, possibly a tolerance level higher. As in Fig. 16 can be seen in the twisted position on the right, the dimension H can be found as an offset 179 on the receiving space 170. The housing pin 23 can penetrate into the receiving space 170 by this offset 179 and thus block further rotation of the locking core 130. H+ is preferably less than 20%, preferably less than 15% and preferably less than 10% larger than H.
- the aforementioned variables determine the scanning function. Starting from an (inner diameter) diameter J of the closing core 130, the maximum width of the receiving space 170 must be determined. Depending on the depth of the receiving space 170, the corresponding depth of the base body 181 located therein can be determined. The offset or the flank height and thus also the stroke H also depend on the width and depth of the receiving space, which ultimately also determines the overhang 15b.
- Fig. 17 shows schematically the exemplary embodiment of a locking core in a perspective view Fig. 2 with a scanning element 180 adapted to production technology.
- the scanning element 180 is manufactured in one piece as a die-cast part.
- the scanning element 180 therefore has recesses 190 for the sprue and overflow during die casting.
- two recesses 191 are provided on the base body 181 and one recess 192 on each tactile projection 182.
- the recesses 191, 192 are formed directly on the side edges, so that they break through them at the respective side edges and thus a recess 191, 192 that is open to at least one side is realized.
- the recesses 192 on the tactile projections 182 form a kind of chamfer at the tip of the respective tactile projection.
- Fig. 18 shows schematically in a perspective view the in Fig. 17 shown, production-technically adapted scanning element 180 alone.
- the recesses 190 for the sprue and overflow can be clearly seen here.
- Each tactile projection 182 has a recess 192 at the end remote from the base body 181.
- the base body 181 has two diametrically opposed recesses 192.
- Fig. 19 shows schematically in a different perspective view the in 17 and 18 shown, production-technically adapted scanning element 180. Except for the recesses 190, this corresponds to the Fig. 17 to 19
- the scanning element 180 shown corresponds to the scanning element 180 shown in the previous figures.
- the recesses 192 can be clearly seen at the end of the tactile projections 182 remote from the base body 181. Due to the cylindrical design of the tactile projections 182, these are designed in a bevel-like manner.

Der Basiskörper weist eine Durchgangsöffnung auf. Die Durchgangsöffnung ist vorzugsweise mittig in dem Basiskörper geformt. Die Durchgangsöffnung erstreckt sich von der Außenseite zur Innenseite bzw. umgekehrt. Dabei ist die Längsachse der Durchgangsöffnung vorzugsweise senkrecht zu der Innenseite ausgerichtet. Die Durchgangsöffnung weist vorzugsweise eine an die Außenkontur des Kernstifts komplementäre Form auf. Insbesondere weist die Durchgangsöffnung eine zylindrische Form auf. Seitlich neben dem Austritt der Durchgangsöffnung an der Innenseite ragt der Tastvorsprung oder ragen die Tastvorsprünge ab. Vorzugsweise ist das Abtastelement einteilig ausgebildet, insbesondere als Guss- oder Spritzgussteil. Bei mehreren Tastvorsprüngen sind diese vorzugsweise gleich, das heißt gleichlang und mit gleicher Kontur ausgebildet. In anderen Ausführungsformen sind die mehreren Tastvorsprünge zumindest teilweise ungleich, das heißt unterschiedlich lang und/oder mit unterschiedlicher Form ausgebildet. Bei einem Einsatz in eine Schließzylinder ist der Schließkern in der Schließkernaufnahme angeordnet. Der Schließkern ist dabei in der Schließkernaufnahme angeordnet, wenn die Schließkernaufnahme und die Kernstiftbohrung koaxial als auch verdreht zueinander angeordnet sind.The invention includes the technical teaching that in a scanning element for a locking core of a locking cylinder for scanning the presence of a sufficient undercut profile rib of a key inserted into a locking channel of the locking core, comprising a base body which has an inside which, when used in a locking core, points towards the locking channel, and an outside which, when used in a locking core, for contacting a locking pin such as a housing pin and/or a cylinder wall of a cylinder bore of a surrounding cylinder housing, it is provided that the base body has a core pin receptacle designed as a through opening in order to receive a core pin of the lock cylinder there when used in a locking cylinder. The base body has a through opening. The through opening is preferably formed centrally in the base body. The through opening extends from the outside to the inside or vice versa. The longitudinal axis of the through opening is preferably aligned perpendicular to the inside. The through opening preferably has a shape that is complementary to the outer contour of the core pin. In particular, the through opening has a cylindrical shape. The tactile projection or tactile projections protrude to the side next to the exit of the through opening on the inside. The scanning element is preferably formed in one piece, in particular as a cast or injection molded part. If there are several tactile projections, these are preferably the same, that is to say of the same length and with the same contour. In other embodiments, the plurality of tactile projections are at least partially unequal, that is to say of different lengths and/or of different shapes. When used in a locking cylinder, the locking core is arranged in the locking core receptacle. The locking core is arranged in the locking core receptacle when the locking core receptacle and the core pin bore are arranged coaxially and rotated relative to one another.
Erfindugsgemäß ragt von der Innenseite des Basiskörpers mindestens ein Tastvorsprung ab, der zum Kontaktieren eines Schlüsselabschnitts eines in den Schließkanal eingesetzten Schlüssels vorgesehen ist, wobei in einer Ausführungsform die Außenseite des Basiskörpers zumindest teilweise abgerundet ist und/oder mindestens zwei unterschiedlich geneigte Seitenabschnitte oder Schrägen aufweist.According to the invention, at least one tactile projection protrudes from the inside of the base body, which is provided for contacting a key section of a key inserted into the locking channel, wherein in one embodiment the outside of the base body is at least partially rounded and / or has at least two differently inclined side sections or bevels.
Das mindestens eine Abtastelement ist vorzugsweise einteilig ausgeführt. In anderen Ausführungsformen kann das Abtastelement aus mehreren Teilen, beispielsweise aus einem separaten Basiskörper und separaten Tastvorsprüngen bestehen. Bei einer einteiligen Ausführungsform ist das Abtastelement bevorzugt als Druckgussteil ausgebildet bzw. mittels Druckgießen hergestellt. Aus fertigungstechnischen Gründen ist an dem Abtastelement mindestens eine Ausnehmung für einen Anguss und Überlauf vorgesehen. Vorzugsweise ist an jedem Ende eines Tastvorsprungs eine Ausnehmung vorgesehen. Weiter bevorzugt ist an dem Basiskörper mindestens eine Ausnehmung vorgesehen, bevorzugt zwei diametral gegenüberliegende Ausnehmungen. Der Basiskörper weist eine Innenseite und eine Außenseite auf. Die Innenseite ist vorzugsweise als eine Ebene ausgebildet, insbesondere als eine plane Ebene. Von der Innenseite, somit der planen Ebene ragt der Tastvorsprung oder ragen die Tastvorsprünge, insbesondere senkrecht ab. Bei einer mehrteiligen Ausführungen können Aufnahmen für Tastvorsprünge vorgesehen sein, aus denen der Tastvorsprung oder die Tastvorsprünge von der Innenseite weg ragt. Der Innenseite gegenüber liegt die Außenseite des Basiskörpers. Die Außenseite ist bei Einsatz in einer Zylinderbohrung eines Schließzylinders derart ausgebildet, dass diese innerhalb der Zylinderbohrung drehbar oder an der Wandung der Zylinderbohrung entlanggleitbar ausgebildet ist. Hierzu ist vorgesehen, dass die Außenseite bzw. der Basiskörper eine Kontur aufweist, welche an die zylindrische Form der Zylinderbohrung zumindest angenähert ist. Hierzu kann der Basiskörper an der Außenseite abgerundet sein, beispielsweise auch mit unterschiedlichen Radien abgerundet sein. In einer anderen Ausführungsform ist der Basiskörper abgeschrägt, insbesondere mit zumindest zwei unterschiedlichen Schrägen abgeschrägt. Der Radius der Abrundung bzw. die Schräge der Abschrägung nimmt von der Innenseite hin zur Außenseite vorzugsweise zu.The at least one scanning element is preferably made in one piece. In other embodiments, the scanning element can consist of several parts, for example a separate base body and separate tactile projections. With a one-piece In this embodiment, the scanning element is preferably designed as a die-cast part or produced by die-casting. For manufacturing reasons, at least one recess for a sprue and overflow is provided on the scanning element. A recess is preferably provided at each end of a sensing projection. More preferably, at least one recess is provided on the base body, preferably two diametrically opposed recesses. The base body has an inside and an outside. The inside is preferably designed as a plane, in particular as a flat plane. From the inside, i.e. the flat plane, the tactile projection or the tactile projections protrude, in particular vertically. In a multi-part design, receptacles for tactile projections can be provided, from which the tactile projection or tactile projections protrude from the inside. Opposite the inside is the outside of the base body. When used in a cylinder bore of a locking cylinder, the outside is designed in such a way that it can be rotated within the cylinder bore or can be slid along the wall of the cylinder bore. For this purpose, it is provided that the outside or the base body has a contour which at least approximates the cylindrical shape of the cylinder bore. For this purpose, the base body can be rounded on the outside, for example also rounded with different radii. In another embodiment, the base body is beveled, in particular beveled with at least two different bevels. The radius of the rounding or the slope of the bevel preferably increases from the inside towards the outside.
Erfindungsgemäß ist vorgesehen, dass der Basiskörper, insbesondere an einer Außenseite beginnend, eine Kernstiftaufnahme zum Aufnehmen und/oder Zusammenwirken mit einem Kernstift aufweist. Die Aufnahme ist vorzugsweise als Durchgangsöffnung, genauer als Durchgangsbohrung, insbesondere als zylindrische Durchgangsbohrung, ausgeführt. Dabei durchdringt die Aufnahme den Basiskörper von der Außenseite zu der Innenseite. Die Aufnahme ist dabei einer Kontur eine Kernstifts angepasst. Die Aufnahme ist vorzugsweise mittig angeordnet. Neben der Innenseite und der Außenseite weist der Basiskörper zwei weitere Seiten auf. Die zwei weiteren Seiten sind vorzugsweise parallel zueinander als Ebenen, insbesondere als plane Ebenen ausgebildet. Die Außenseite geht nahezu in die Innenseite über, sodass der Basiskörper im Wesentlichen vier Seiten - Außenseite, Innenseite, zwei seitliche Seiten aufweist. Der Übergang von Außenseite zur Innenseite erfolgt allenfalls über flächenmäßig kleinere Seitenübergänge.According to the invention it is provided that the base body, in particular starting on an outside, has a core pin receptacle for receiving and/or interacting with a core pin. The receptacle is preferably designed as a through opening, more precisely as a through hole, in particular as a cylindrical through hole. The receptacle penetrates the base body from the outside to the inside. The recording is adapted to a contour of a core pin. The receptacle is preferably arranged in the middle. In addition to the inside and the outside, the base body has two additional sides. The two further sides are preferably designed parallel to one another as planes, in particular as flat planes. The outside almost merges into the inside, so that the base body essentially has four sides - outside, inside, two side sides. The transition from the outside to the inside takes place via side transitions that are smaller in area.
Noch eine Ausführungsform sieht vor, dass von der Innenseite des Basiskörpers zwei in der Ebene der Innenseite voneinander beabstandete, diagonal gegenüberliegende Tastvorsprünge abragen. Die Tastvorsprünge sind in einer Ausführungsform einteilig mit dem Basiskörper ausgebildet. In einer anderen Ausführungsform sind die Tastvorsprünge separat zu dem Basiskörper ausgebildet und mit diesem verbunden ausgeführt. Das Abtastelement weist mindestens einen Tastvorsprung auf. Bevorzugt weist das Abtastelement zwei Tastvorsprünge auf. Die Tastvorsprünge ragen vorzugsweise etwa senkrecht von der Innenseite ab. Vorzugsweise ist der mindestens eine Tastvorsprung zylindrisch, beispielsweise als Zylinderstift oder Zylinderstiftabschnitt ausgebildet. Der Tastvorsprung kann aber auch insbesondere in Abhängigkeit von der Tastfunktion andere Formen aufweisen. Das Abtastelement ist zum Einlegen oder Einsetzen in einen Schließkern vorgesehen, um dort eine Tastfunktion zu übernehmen. Vorzugsweise sind die Tastvorsprünge gleich lang ausgebildet. In anderen Ausführungsformen sind die Tastvorsprünge unterschiedlich lang ausgebildet.Another embodiment provides that two diagonally opposite tactile projections that are spaced apart from one another in the plane of the inside protrude from the inside of the base body. In one embodiment, the tactile projections are formed in one piece with the base body. In another embodiment, the tactile projections are designed separately from the base body and are connected to it. The scanning element has at least one sensing projection. The scanning element preferably has two sensing projections. The tactile projections preferably protrude approximately vertically from the inside. Preferably, the at least one tactile projection is cylindrical, for example designed as a cylindrical pin or cylindrical pin section. However, the tactile projection can also have other shapes, particularly depending on the tactile function. The scanning element is intended to be inserted or inserted into a locking core in order to take on a tactile function there. The tactile projections are preferably of the same length. In other embodiments, the tactile projections are of different lengths.
Die Erfindung schließt auch die technische Lehre ein, dass bei einem Schließkern für einen Schließzylinder vorgesehen ist, dass der Schließkern einen profilierten Schließkanal zum Zusammenwirken mit einem Schlüssel, genauer einem seitlichen Schlüsselprofil aufweist, wobei der Schließkern mindestens eine Kernstiftbohrung aufweist, welche in den Schließkanal mündet, und wobei der Schließkern einen Aufnahmeraum für einen Abtastelement zum Abtasten einer hinterschnittenen, insbesondere einer ausreichend hinterschnittenen, Profilrippe eines in den Schließkanal eingesteckten Schlüssels aufweist, wobei der Aufnahmeraum einen Basisraum aufweist, in welchem ein Basiskörper des Abtastelements einlegbar ist oder eingelegt ist, und einen mit dem Basisraum zur Bildung des Aufnahmeraums verbundenen Vorsprungraum aufweist, der seitlich zumindest teilweise, insbesondere über 8 Prozent der Gesamtlänge des Vorsprungraums, in den Schließkanal durchbricht, in den ein Tastvorsprung des Abtastelements bei eingesetztem Abtastelement ragt, wobei der Basisraum und/oder der Vorsprungraum in Richtung der Achse der Kernstiftbohrung ein größeres Abtastabmaß als der Basiskörper und/oder als der Tastvorsprung bei eingesetztem Abtastelement aufweist/aufweisen, sodass ein Tastraum zumindest in dem Vorsprungraum realisiert ist, in dem bei eingesetztem Abtastelement dieses in Richtung der Achse der Kernstiftbohrung bewegbar ist, sofern ein in den Tastraum ragender Schlüsselabschnitt keine die Bewegung sperrende hinterschnittene Profilrippe aufweist. Das Abtastelement des Schließkerns ist dabei als hier beschriebenes Abtastelement ausgebildet. Ein Schließkern mit profiliertem Schließkanal und Kernstiftbohrung zudem mit Kernstiften und Gehäusestiften, allgemein also mit Sperrstiften, aber ohne Aufnahmeraum, ist grundsätzlich aus dem Stand der Technik bekannt. Der Aufnahmeraum ist zur Aufnahme eines Abtastelements ausgebildet. Dabei ist der Aufnahmeraum an die Kontur des Abtastelements angepasst, wobei Toleranzen vorgesehen sind, sodass das Abtastelement innerhalb des Aufnahmeraums zumindest in eine Richtung, vorzugsweise eine axiale Richtung der Kernbohrung, bewegbar ist. Entsprechend weist der Aufnahmeraum einen Basisraum auf, der an den Basiskörper des Abtastelements angepasst ist, und einen Vorsprungraum, der an den Tastvorsprung oder die Tastvorsprünge angepasst ist. Der Aufnahmeraum und der Vorsprungraum sind in axiale Richtung der Kernbohrung größer Bemessen, als der Basiskörper bzw. der jeweilige Tastvorsprung, sodass eine Freiheitsgrad für eine Bewegung des Abtastelements in axiale Richtung der Kernbohrung ermöglicht ist. Dabei ist der Aufnahmeraum in axiale Richtung der Kernbohrung um eine Abtastmaß größer bemessen als der korrespondierende Bereich des Abtastelements. Es ist somit ein Raum für einen Hub des Abtastelements ausgebildet. Der Vorsprungraum bricht dabei in den Schließkanal durch, sodass eine (hinterschnittene) Profilrippe eines eingesetzten profilierten Schlüssels durch den Schließkanal in den Vorsprungraum ragen kann oder ragt, genauer in einen Tastraum, der in axiale Richtung der Kernbohrung durch das Abtastmaß definiert wird. Dabei bricht der Vorsprungraum und/oder der Abtastraum zu mindestens 8 Prozent der Gesamtlänge des Vorsprungraums und/oder des Abtastraums seitlich in den Schließkanal durch. Insbesondere beträgt der seitliche Durchbruch mindestens 10 Prozent, bevorzugt mindestens 15 Prozent, noch weiter bevorzugt mindestens 20 Prozent und am meisten bevorzugt mindestens 40 Prozent der Gesamtlänge des Vorsprungraums und/oder des Abtastraums. Im Wesentlichen bricht der Vorsprungraum / Abtastraum seitlich in den Schließkanal durch.The invention also includes the technical teaching that in a locking core for a locking cylinder it is provided that the locking core has a profiled locking channel for interaction with a key, more precisely a side key profile, the locking core having at least one core pin hole which opens into the locking channel , and wherein the locking core has a receiving space for a scanning element for scanning an undercut, in particular a sufficiently undercut, profile rib of a key inserted into the locking channel, the receiving space having a base space in which a base body of the scanning element can be inserted or is inserted, and one has a projection space connected to the base space to form the receiving space, which laterally breaks through at least partially, in particular over 8 percent of the total length of the projection space, into the closing channel, into which a sensing projection of the sensing element projects when the sensing element is inserted, the base space and/or the projection space in In the direction of the axis of the core pin bore, a larger scanning dimension than the base body and/or than the sensing projection when the sensing element is inserted, so that a sensing space is realized at least in the projection space in which, when the sensing element is inserted, it can be moved in the direction of the axis of the core pin bore, provided a key section protruding into the sensing area, no undercut profile rib blocking the movement having. The scanning element of the locking core is designed as a scanning element described here. A locking core with a profiled locking channel and core pin hole, also with core pins and housing pins, generally with locking pins but without a receiving space, is basically known from the prior art. The receiving space is designed to accommodate a scanning element. The receiving space is adapted to the contour of the scanning element, with tolerances being provided so that the scanning element can be moved within the receiving space at least in one direction, preferably an axial direction, of the core bore. Accordingly, the receiving space has a base space that is adapted to the base body of the scanning element, and a projection space that is adapted to the tactile projection or tactile projections. The receiving space and the projection space are dimensioned larger in the axial direction of the core hole than the base body or the respective sensing projection, so that a degree of freedom for movement of the scanning element in the axial direction of the core bore is possible. The receiving space in the axial direction of the core bore is dimensioned to be one scanning dimension larger than the corresponding area of the scanning element. A space is thus formed for a stroke of the scanning element. The projection space breaks through into the locking channel, so that an (undercut) profile rib of an inserted profiled key can or projects through the locking channel into the projection space, more precisely into a sensing space which is defined in the axial direction of the core bore by the scanning dimension. The projection space and/or the scanning space breaks through laterally into the closing channel by at least 8 percent of the total length of the projection space and/or the scanning space. In particular, the lateral breakthrough is at least 10 percent, preferably at least 15 percent, even more preferably at least 20 percent and most preferably at least 40 percent of the total length of the projection space and/or the scanning space. Essentially, the projection space/scanning space breaks through laterally into the locking channel.
In einer Ausführungsform ist vorgesehen, dass das Abtastabmaß bzw. der Tastraum so bemessen ist, dass bei einem eingesetztem Schlüssel mit ausreichend hinterschnittener Profilrippe die Profilrippe in den Abtastraum ragt, insbesondere seitlich in den Abtastraum ragt, und wenn der Tastvorsprung an der in den Abtastraum ragenden ausreichend hinterschnittenen Profilrippe des Schlüssels anschlägt, die Außenseite des Basiskörper zumindest im Bereich der Kernstiftbohrung bündig mit der Außenkontur des die Kernstiftbohrung umgebenden Bereichs des Gehäusestifts und/oder Zylindergehäuses abschließt, sodass ein Eindringen des Gehäusestifts in den Aufnahmeraum verhindert ist. Bei einem Schlüssel mit einer hinterschnittenen Profilrippe ragt der vorderer Teil der Profilrippe von der Spitze bis zu dem Hinterschnitt, genauer mit einem Überhang der hinterschnittenen Profilrippe in den Tastraum. Die Profilrippe hat bei Einsatz in dem Schließkanal in axiale Richtung der Kernbohrung ein Profilmaß, welches kleiner oder gleich, bevorzugt etwa in der Größenordnung des Abtastmaßes und kleiner, ist. Entsprechend kann der Teil der Profilrippe zwischen Spitze oder äußerem Ende und Hinterschnitt in den Tastraum ragen und dort von dem Abtastelement abgetastet werden. Durch den Hinterschnitt ist also an der Spitze der Profilrippe ein Übermaß, Vorsprung oder Überhang der Profilrippe ausgebildet, welches bzw. welcher in dem Tastraum abgefragt bzw. abgetastet wird. Bei Profilrippen ohne Hinterschnitt ist dieses Übermaß kleiner als das Abtastmaß bis hin zu 0 mm. Der Tastraum ist somit nicht oder nur unzureichend mit der Profilrippe belegt bzw. der Tastvorsprung schlägt nicht an der Profilrippe, sondern an der Endwand des Vorsprungraums entfernt von dem Basisraum an. Somit grenzt auch der Basiskörper an einer inneren Wandung des Aufnahmeraums an und es entsteht durch die Flanken des Aufnahmeraums ein Versatz im Bereich des Sperrstiftes, genauer des Gehäusestiftes, um diesen der Gehäusestift in den Aufnahmeraum eindringen kann. Hierdurch wird eine Drehung des Schließkerns in der Zylinderbohrung des Schließzylinders bei einem Einsatz in dem Schließzylinder über einen bestimmten Drehwinkel hinaus verhindert. Der Drehwinkel wird über die Größe des Aufnahmeraums festgelegt. Die vorliegende Erfindung ermöglicht es, dass sich der Schließkern wieder zurück drehen lässt und nicht in seiner verdrehten Position gefangen ist. Hierdurch lässt sich auch ein Schlüssel mit nicht (ausreichend) hinterschnittener Profilierung / Profilrippe nach Zurückdrehen wieder aus dem Schließkanal herausziehen. Ausreichend hinterschnitten beschreibt somit einen durch Hinterschnitt geformten Überhang, der einen Abtastraum dermaßen belegt, dass ein daran angrenzendes Abtastelement eine Drehung des Schließkerns ab einem vorbestimmten Drehwinkel hemmt. Derartige Hinterschnitte oder entsprechende Überhänge weisen in axiale Richtung der Kernstiftbohrung ein Abmaß auf, welches vorzugsweise über 0,1 mm, weiter bevorzugt über 0,2 mm und am meisten bevorzugt über 0,3 mm liegt. Vorzugsweise ist das Abmaß bevorzugt kleiner als 5 mm, weiter bevorzugt kleiner als 4 mm und am meisten bevorzugt kleiner als 3 mm. Das Abmaß kann aber abhängig von der Größenordnungen von Schließkern, Schlüssel etc. auch davon abweichende Werte annehmen. Unter einer hinterschnittenen Profilrippe ist somit immer eine ausreichend hinterschnittene Profilrippe zu verstehen, die eine Überhang aufweist, mit dem die Tastfunktion realisierbar ist. Die Rippe ragt bevorzugt durch den seitlichen Durchbruch in den Abtastraum / Vorsprungraum.In one embodiment it is provided that the scanning dimension or the scanning space is dimensioned such that when a key is inserted with a sufficiently undercut profile rib, the profile rib projects into the scanning space, in particular protrudes laterally into the scanning space, and when the scanning projection protrudes into the scanning space sufficiently undercut profile rib of the key, the outside of the base body at least in the area of the core pin hole is flush with the outer contour of the area of the housing pin and / or cylinder housing surrounding the core pin hole closes so that the housing pin is prevented from penetrating into the receiving space. In the case of a key with an undercut profile rib, the front part of the profile rib protrudes from the tip to the undercut, more precisely with an overhang of the undercut profile rib into the tactile area. When used in the closing channel in the axial direction of the core bore, the profile rib has a profile dimension which is smaller or equal to, preferably approximately in the order of magnitude of the scanning dimension and smaller. Accordingly, the part of the profile rib between the tip or outer end and the undercut can protrude into the scanning space and be scanned there by the scanning element. Due to the undercut, an excess, projection or overhang of the profile rib is formed at the tip of the profile rib, which is queried or scanned in the scanning space. For profile ribs without undercut, this excess dimension is smaller than the measuring dimension up to 0 mm. The sensing space is therefore not or only insufficiently occupied by the profile rib or the sensing projection does not strike the profile rib but rather the end wall of the projection space away from the base space. The base body therefore also borders on an inner wall of the receiving space and the flanks of the receiving space create an offset in the area of the locking pin, more precisely the housing pin, around which the housing pin can penetrate into the receiving space. This prevents the locking core from rotating in the cylinder bore of the locking cylinder beyond a certain angle of rotation when used in the locking cylinder. The angle of rotation is determined by the size of the recording space. The present invention allows the locking core to rotate back and not be caught in its twisted position. This means that even a key with an insufficiently undercut profile/profile rib can be pulled out of the locking channel after turning it back. Sufficiently undercut therefore describes an overhang formed by an undercut, which occupies a scanning space in such a way that an adjacent scanning element inhibits rotation of the locking core from a predetermined angle of rotation. Such undercuts or corresponding overhangs have a dimension in the axial direction of the core pin bore which is preferably over 0.1 mm, more preferably over 0.2 mm and most preferably over 0.3 mm. Preferably, the dimension is preferably smaller than 5 mm, more preferably smaller than 4 mm and most preferably smaller than 3 mm. However, depending on the dimensions of the locking core, key, etc., the dimensions can also take on different values. An undercut profile rib is therefore always to be understood as a sufficiently undercut profile rib that has an overhang which the touch function can be implemented. The rib preferably protrudes through the side opening into the scanning space/protrusion space.
Die Erfindung sieht vor, dass das Abtastelement des Schließkerns nach einem vorstehend beschriebenen Abtastelement ausgebildet ist. In einer Ausführungsform ist vorgesehen, dass der Aufnahmeraum des Schließkerns angepasst an das Abtastelement zur Aufnahme des Abtastelements mit Vorsehen des Tastraums und Bewegung hin und weg zu dem Tastraum ausgebildet ist. Der Aufnahmeraum ist vorzugsweise komplementär zu dem Abtastelement ausgebildet, weist aber zusätzlich das Abtastmaß oder den Hub auf, das heißt ist in axiale Richtung der Kernbohrung größer bemessen, als das Abtastelement bzw. der Tastvorsprung. Hierdurch ist eine lineare Bewegung in axiale Richtung der Kernbohrung möglich.The invention provides that the scanning element of the locking core is designed according to a scanning element described above. In one embodiment it is provided that the receiving space of the locking core is adapted to the scanning element for receiving the scanning element with provision of the scanning space and movement back and away to the scanning space. The receiving space is preferably designed to be complementary to the scanning element, but also has the scanning dimension or the stroke, that is to say it is larger in the axial direction of the core bore than the scanning element or the scanning projection. This allows a linear movement in the axial direction of the core hole.
Zudem schließt die Erfindung die technische Lehre ein, dass bei einem Abtastmechanismus für einen Schließzylinder, mit einem Schließkern, der einen Schließkanal aufweist, in den ein korrespondierender Schlüssel einsteckbar ist, der mindestens eine als Durchgangsöffnung ausgebildete Kernstiftbohrung aufweist und der einen Aufnahmeraum aufweist, in dem eine Abtastelement aufgenommen ist, vorgesehen ist, das das Abtastelement fluchtend zu der Kernstiftbohrung eine Kernstiftaufnahme aufweist, wobei in der mindestens einen Kernstiftbohrung und der Kernstiftaufnahme ein Kernstift aufnehmbar und/oder aufgenommen ist, wobei der Aufnahmeraum einen Tastraum ausbildet, der in den Schließkanal durchbricht oder in den Schließkanal ragt, sodass ein korrespondierender Schlüsselabschnitt eines in den Schließkanal eingesetzten Schlüssels in den Tastraum ragt oder ragen kann, sodass das Abtastelement im Bereich des Tastraums gegen den korrespondierenden, in den Tastraum hineinragenden Schlüsselabschnitt anschlägt oder anschlagen kann, wobei der Tastraum so bemessen ist, dass wenn der korrespondierende Schlüsselabschnitt eine ausreichend hinterschnittene Profilrippe aufweist, das Abtastelement einerseits an der Profilrippe anliegt und andererseits zumindest teilweise bündig mit einer Außenseite des Schließkerns abschließt und wenn der Schlüsselabschnitt keine ausreichend hinterschnittene Profilrippe aufweist, das Abtastelement wenn es an dem Schlüsselabschnitt anschlägt andererseits versetzt, insbesondere nach innen versetzt zu der Außenseite des Schließkerns angeordnet ist. Das Abtastelement ist nach einem hier beschriebenen Abtastelement ausgebildet. Der Abtastmechanismus funktioniert wie folgt. Ein Schlüssel wird in den Schließkanal des Schließkerns eingesteckt. Bei einem Schlüssel mit (ausreichend) hinterschnittener Profilrippe ragt der vordere Teil der Profilrippe, vorzugsweise der Schüsselabschnitt von der Spitze bis zum Hinterschnitt der Profilrippe, insbesondere der Überhang, in den Tastraum. Mit dem in den Tastraum ragenden Schlüsselabschnitt oder Überhang grenzt der Schlüsselabschnitt an den in axiale Kernbohrungsrichtung zugehörigen Tastvorsprung an. Hierdurch wird das Abtastelement in axiale Richtung der Kernbohrung nach außen in Richtung Wandung Zylinderbohrung gedrückt, wodurch ein Versatz zwischen Außenseite und Flanken des Aufnahmeraums verhindert wird. Der Gehäusestift grenzt an die Außenseite an, ohne eine Drehbewegung des Schließkerns in der Zylinderbohrung zu verhindern. Dagegen ist bei Einsatz eines Schlüssels ohne (ausreichend) hinterschnittene Profilrippe die Drehbewegung ab einem gewissen Drehwinkel blockiert. Der Schlüssel ohne (ausreichend) hinterschnittene Profilrippe wird in den Schließkanal gesteckt. Die entsprechende Profilrippe ragt allenfalls mit einem geringen Anteil in den Tastraum, wodurch der entsprechende Tastvorsprung entweder an der Endwandung des Tastraums anliegt oder an dem nicht für eine Blockierung ausreichenden Teil der nicht (ausreichend) hinterschnittenen Profilrippe. Hierdurch ist ein Absatz im Bereich der Außenseite des Basiskörpers zu dem angrenzenden Umfang des Zylinderkerns gebildet, sodass der Gehäusestift teilweise in den Aufnahmeraum eindringen kann und eine Drehbewegung durch Anschlag an die Flanken des Aufnahmeraums ab einem vorbestimmten Drehwinkel blockiert ist. Der Schließkern lässt sich in eine Richtung zum Öffnen nicht weiter drehen, sondern lediglich zurück in die Ausgangsposition, in welcher der Schlüssel in den Schließkanal eingesteckt wurde. Der Aufnahmeraum ist bevorzugt symmetrisch zu der Kernbohrung ausgebildet, sodass ein Drehen in und entgegen Uhrzeigersinn möglich ist, begrenzt durch das entsprechende Maß des Aufnahmeraums. Der Kernstift ist dabei stets in der Kernstiftaufnahme des Basiskörpers aufgenommen. Dabei durchdringt der Kernstift die Kernstiftaufnahme des Basiskörper und ragt in Richtung Schlüssel über den Basiskörper vor. An der Außenseite des Basiskörpers schließt der Kernstift mit der Außenkontur ab, sofern im verdrehten Zustand eine ausreichend hinterschnittene Profilrippe an einem Schlüssel vorhanden ist oder ragt über die Außenkontor der Außenseite hervor, sofern ein Schlüssel mit unzureichend hinterschnittener Profilrippe vorhanden ist. Der Kernstift grenzt im verdrehten Zustand an der Außenseite des Basiskörpers an die Wandung der Schließkernbohrung an.In addition, the invention includes the technical teaching that in a scanning mechanism for a locking cylinder, with a locking core which has a locking channel into which a corresponding key can be inserted, which has at least one core pin hole designed as a through opening and which has a receiving space in which a scanning element is accommodated, it is provided that the scanning element has a core pin receptacle aligned with the core pin bore, a core pin being receivable and/or accommodated in the at least one core pin bore and the core pin receptacle, the receiving space forming a sensing space which breaks through into the locking channel or protrudes into the locking channel, so that a corresponding key section of a key inserted into the locking channel protrudes or can protrude into the sensing space, so that the scanning element in the area of the sensing space strikes or can strike against the corresponding key section protruding into the sensing space, the sensing space being dimensioned in this way that if the corresponding key section has a sufficiently undercut profile rib, the scanning element rests on the one hand on the profile rib and on the other hand is at least partially flush with an outside of the locking core and if the key section does not have a sufficiently undercut profile rib, the scanning element is offset when it hits the key section , in particular is arranged offset inwards to the outside of the locking core. The scanning element is designed according to a scanning element described here. The scanning mechanism works as follows. A key is inserted into the locking channel of the locking core. On a key with a (sufficiently) undercut profile rib, the front part of the profile rib protrudes, preferably the bowl section from the tip to the undercut of the profile rib, especially the overhang, into the sensing space. With the key section or overhang protruding into the sensing space, the key section adjoins the sensing projection associated in the axial core drilling direction. As a result, the scanning element is pressed outwards in the axial direction of the core bore towards the wall of the cylinder bore, thereby preventing an offset between the outside and the flanks of the receiving space. The housing pin adjoins the outside without preventing rotation of the locking core in the cylinder bore. On the other hand, when using a key without a (sufficiently) undercut profile rib, the rotational movement is blocked from a certain angle of rotation. The key without a (sufficiently) undercut profile rib is inserted into the locking channel. The corresponding profile rib protrudes at most into the sensing space to a small extent, whereby the corresponding sensing projection rests either on the end wall of the sensing space or on the part of the profile rib that is not (sufficiently) undercut that is not sufficient for blocking. As a result, a shoulder is formed in the area of the outside of the base body to the adjacent circumference of the cylinder core, so that the housing pin can partially penetrate into the receiving space and a rotational movement is blocked by abutting the flanks of the receiving space from a predetermined angle of rotation. The locking core cannot be rotated further in a direction to open, but only back to the starting position in which the key was inserted into the locking channel. The receiving space is preferably designed symmetrically to the core bore, so that rotation in and counterclockwise is possible, limited by the corresponding dimension of the receiving space. The core pin is always accommodated in the core pin receptacle of the base body. The core pin penetrates the core pin receptacle of the base body and protrudes over the base body in the direction of the key. On the outside of the base body, the core pin closes with the outer contour if there is a sufficiently undercut profile rib on a key in the twisted state or protrudes beyond the outer contour of the outside if there is a key with an insufficiently undercut profile rib. When twisted, the core pin adjoins the wall of the locking core bore on the outside of the base body.
In einer Ausführungsform ist vorgesehen, dass ein in Richtung Schließkern vorgespanntes Stiftelement in Richtung Abtastelement wirkt. Das Stiftelement ist als Sperrstift mit einem Kernstift und einem Gehäusestift ausgebildet. Der Gehäusestift ist über eine Feder vorgespannt und drückt in Richtung Zylinderkern, wodurch auch der Kernstift in die gleiche Richtung gezwungen wird. Feder und Gehäusestift sind in einer entsprechenden Aufnahme in dem Zylindergehäuse aufgenommen. Der Kernstift ist in der Kernbohrung des Schließkerns aufgenommen. Ohne eingesetzten Schlüssel ragt der Gehäusestift in die Kernbohrung. Die Kernbohrung setzt sich von dem Aufnahmeraum in Richtung Zentrum Schließkern fort. Entsprechend wird der Gehäusestift auch stets in den Aufnahmeraum gezwungen, sofern hier nicht ein eingesetzter Schlüssel entgegenwirkt.In one embodiment it is provided that a pin element prestressed in the direction of the locking core acts in the direction of the scanning element. The pin element is designed as a locking pin with a core pin and a housing pin. The housing pin is via a spring preloaded and pushes towards the cylinder core, which also forces the core pin in the same direction. The spring and housing pin are accommodated in a corresponding receptacle in the cylinder housing. The core pin is accommodated in the core hole of the locking core. Without the key inserted, the housing pin protrudes into the core hole. The core drilling continues from the receiving space towards the center of the locking core. Accordingly, the housing pin is always forced into the receiving space unless an inserted key counteracts it.
Eine weitere Ausführungsform sieht vor, dass der Schließkern nach einem hier beschriebenen Schließkern ausgebildet ist.A further embodiment provides that the locking core is designed according to a locking core described here.
Auch schließt die Erfindung die technische Lehre ein, dass bei einem Schließzylinder, umfassend ein Zylindergehäuse, das eine Schließkernbohrung aufweist, in der drehbar ein Schließkern aufgenommen ist, vorgesehen ist, dass der Schließkern einen Schließkanal und mindestens eine in den Schließkanal mündende Kernstiftbohrung aufweist wobei das Zylindergehäuse mindestens einen in einer quer zu der Schließkernbohrung ausgebildeten, in die Schließkernbohrung und fluchtend in die Kernbohrung mündenden Stiftkanal aufweist, und wobei eine Stifteinheit mit einem in Richtung Schließkern federvorgespannten Gehäusestift und einem in der Kernbohrung einliegenden, an dem Gehäusestift angrenzenden Kernstift, wobei der Schließkern einen Aufnahmeraum mit einem Tastraum aufweist, in dem ein axial zu der Schließkernbohrung bewegliches Abtastelement angeordnet ist, wobei das Abtastelement eine zu der Kernstiftbohrung fluchtende Kernstiftaufnahme zur Aufnahme des Kernstifts aufweist, wobei der Aufnahmeraum zumindest teilweise im Bereich des Tastraums zu dem Schließkanal durchbrochen, insbesondere zu mindestens 8 Prozent der Gesamtlänge des Abtastraums und/oder des Vorsprungraums seitlich durchbrochen ist, so dass ein Schlüsselabschnitt seitlich in den Tastraum des Aufnahmeraums bei in den Schließkanal eingesetztem Schlüssel ragt, wobei der Aufnahmeraum und/oder der Tastraum so bemessen ist/sind, dass das Abtastelement in dem Aufnahmeraum axial zu der Kernstiftbohrung bewegbar ist, wenn ein Schlüsselabschnitt ohne (ausreichenden) Hinterschnitt in den Schließkanal und/oder in den Tastraum ragt und/oder wobei insbesondere ein Schließkern nach einem hier beschriebene Schließkern ausgebildet ist, der in der Schließkernbohrung aufgenommen ist. Der Schlüsselabschnitt, insbesondere die hinterschnittene Profilrippe ragt durch den seitlichen Durchbruch in den Abtastraum / Vorsprungsraum. Das Abtastelement ist nach einem hier beschriebenen Abtastelement ausgebildet.The invention also includes the technical teaching that in a locking cylinder, comprising a cylinder housing which has a locking core bore in which a locking core is rotatably accommodated, it is provided that the locking core has a locking channel and at least one core pin bore opening into the locking channel Cylinder housing has at least one pin channel formed transversely to the locking core bore, opening into the locking core bore and aligned into the core bore, and wherein a pin unit with a housing pin spring-loaded in the direction of the locking core and a core pin lying in the core bore and adjacent to the housing pin, the locking core has a receiving space with a sensing space in which a sensing element movable axially to the locking core bore is arranged, the sensing element having a core pin receptacle aligned with the core pin bore for receiving the core pin, the receiving space being at least partially broken through in the area of the sensing space to the locking channel, in particular closed at least 8 percent of the total length of the scanning space and/or the projection space is pierced laterally, so that a key section protrudes laterally into the sensing space of the receiving space when the key is inserted into the locking channel, the receiving space and/or the sensing space being/are dimensioned such that Scanning element in the receiving space can be moved axially to the core pin bore if a key section without (sufficient) undercut protrudes into the locking channel and/or into the sensing space and/or in particular a locking core is designed according to a locking core described here, which is received in the locking core bore . The key section, in particular the undercut profile rib, protrudes through the side Breakthrough into the sampling space/projection space. The scanning element is designed according to a scanning element described here.
In einer Ausführungsform ist vorgesehen, dass ein Abtastmechanismus nach einem hier beschriebenen Abtastmechanismus vorgesehen ist.In one embodiment it is provided that a scanning mechanism is provided according to a scanning mechanism described here.
Weiter schließt die Erfindung die technische Lehre ein, dass bei einem Schließsystem, umfassend einen Schließzylinder, insbesondere einen hier beschriebenen Schließzylinder und/oder ein Abtastelement, insbesondere ein hier beschriebenes Abtastelement und/oder einen Abtastmechanismus, insbesondere einen hier beschriebenen Abtastmechanismus und/oder einen Schließkern, insbesondere einen hier beschriebenen Schließkern, vorgesehen ist, dass ein Schließkanal vorgesehen ist und ein für einen Schließkanal, insbesondere einen Schließkanal des Schließzylinders, des Schließkerns und/oder des Abtastmechanismus, passenden Schlüssel vorgesehen ist.The invention further includes the technical teaching that in a locking system comprising a locking cylinder, in particular a locking cylinder described here and/or a scanning element, in particular a scanning element described here and/or a scanning mechanism, in particular a scanning mechanism described here and/or a locking core , in particular a locking core described here, it is provided that a locking channel is provided and a key suitable for a locking channel, in particular a locking channel of the locking cylinder, the locking core and / or the scanning mechanism, is provided.
In einem Beispiel ist vorgesehen, dass der Schlüssel hinterschnittsfrei ausgebildet ist. Der Schlüssel weist somit keinen (ausreichend dimensionierten) Überhang auf.In one example it is provided that the key is designed to be free of undercuts. The key therefore has no (sufficiently dimensioned) overhang.
In einem anderen Beispiel ist vorgesehen, dass der Schlüssel mit mindestens einem Hinterschnitt ausgebildet ist. Der Schlüssel weist somit einen (ausreichend dimensionierten) Überhang auf.In another example it is provided that the key is designed with at least one undercut. The key therefore has a (sufficiently dimensioned) overhang.
Das Schließsystem funktioniert zu einem gewissen Grad sowohl mit hinterschnittsfreien und mit hinterschnittenen Schlüsseln. Bei hinterschnittsfreien Schlüsseln lässt sich der Schließkern bis zu einem vorbestimmten Drehwinkel C drehen und nicht weiter, dafür aber wieder zurück. Der hinterschnittsfreien Schlüssel lässt sich nach Zurückdrehen aus dem Schließzylinder entnehmen und ist nicht gefangen. Mit einem hinterschnittenen Schlüssel mit entsprechendem Überhang lässt sich der Schließkern über den vorbestimmten Drehwinkel C hinaus drehen und die vollständige Schließfunktion lässt sich realisieren.The locking system works to a certain extent with both undercut-free and undercut keys. With undercut-free keys, the locking core can be turned up to a predetermined angle of rotation C and no further, but back again. The undercut-free key can be removed from the lock cylinder after being turned back and is not caught. With an undercut key with a corresponding overhang, the locking core can be rotated beyond the predetermined angle of rotation C and the complete locking function can be implemented.
Ein weiteres Beispiel sieht vor, dass der Hinterschnitt in axialer Richtung einer Schließkernbohrung so bemessen ist, dass ein an eine den Hinterschnitt aufweisende Profilrippe angrenzendes Abtastelement mit einer anderen Seite bündig mit einer Außenseite des Kernstift ist.A further example provides that the undercut is dimensioned in the axial direction of a locking core bore such that a scanning element adjacent to a profile rib having the undercut is flush with an outside of the core pin on another side.
Nicht zuletzt schließt die Erfindung die technische Lehre ein, dass bei einem Verfahren zum Abtasten einer hinterschnittenen Profilrippe eines in einen Schließkanal eines Schließkerns eingesteckten Schlüssels, insbesondere eines hier beschriebenen Schließkerns, eines hier beschriebenen Schließkerns eines hier beschriebenen Abtastmechanismus, eines hier beschriebenen Schließkerns eines hier beschriebenen Schließzylinders und/oder eines hier beschriebenen Schließsystems, vorgesehen ist, dass die Schritte umfasst sind: Einstecken eines Schlüssels in den Schließkanals des Schließkerns, sodass ein Schlüsselabschnitt, insbesondere ein seitlicher Schlüsselabschnitt in einen Tastraum eines Aufnahmeraums des Schließkerns ragt, wobei bei dem Einstecken im Falle, dass der Schlüssel an dem Abschnitt, der in den Tastraum ragt, eine ausreichend hinterschnittene Profilrippe aufweist, das in dem Abtastraum bewegbar angeordneten Abtastelement kontaktiert wird und das Abtastelement in Richtung Außenseite Schließkern bewegt wird, sodass der Abtastelement bündig oder nahezu bündig mit der Außenseite des Schließkerns abschließt und im Falle, dass der Schlüssel in dem der Schlüsselabschnitt, der in den Tastraum ragt, keine ausreichend hinterschnittene Profilrippe aufweist, das in dem Abtastraum bewegbar angeordnete Abtastelement kontaktiert wird und das Abtastelement allenfalls derart bewegt wird, dass dieses versetzt, insbesondere nach innen in Richtung Abtastraum versetzt angeordnet wird.Last but not least, the invention includes the technical teaching that in a method for scanning an undercut profile rib of a key inserted into a locking channel of a locking core, in particular a locking core described here, a locking core described here, a scanning mechanism described here, a locking core described here, a locking core described here Locking cylinder and / or a locking system described here, it is provided that the steps include: inserting a key into the locking channel of the locking core, so that a key section, in particular a side key section, protrudes into a tactile space of a receiving space of the locking core, during insertion in the case that the key has a sufficiently undercut profile rib on the section that protrudes into the scanning space, the scanning element movably arranged in the scanning space is contacted and the scanning element is moved towards the outside of the locking core, so that the scanning element is flush or almost flush with the outside of the Locking core closes and in the event that the key in which the key section that protrudes into the scanning space does not have a sufficiently undercut profile rib, the scanning element movably arranged in the scanning space is contacted and the scanning element is at most moved in such a way that it is offset, in particular inwards is arranged offset in the direction of the scanning space.
Eine Ausführungsform sieht vor, dass das Verfahren mit einem hier beschriebenen Schließkern, einem hier beschriebenen Abtastmechanismus, einem hier beschriebenen Schließzylinder, einem hier beschriebenen Schlüssels und/oder einem hier beschriebenen Schließsystems durchgeführt wird.One embodiment provides that the method is carried out with a locking core described here, a scanning mechanism described here, a locking cylinder described here, a key described here and/or a locking system described here.
